A lot more people than you probably think really do know, appreciate,and respect the field of human factors and ergonomics (HF/E).2. What our members do really makes a difference in the world.We human factors specialists and ergonomists often lamentthat people do not understand what we do or that we get too littlerespect from industry or from government entities. However,once I started to pay attention to the prevalence of HF/E in societyat large, I was struck by the magnitude of the presence that thefield really has.Plenty of Evidence of HF/E ImpactThe Department of Defense, for example, has long paid attentionto the importance of matching the characteristics, capabilities,and limitations of users with the design of systems, selectionof personnel, and development of training programs. In fact, thehistory of the HF/E field in this country has its roots in the eventssurrounding World Wars I and II.A couple of years ago at the American Telemedicine Associationmeeting, the keynote speaker was General James Peake, thenSurgeon General of the Army. The entire theme of his presentationwas “It’s all about the user.” That level of recognition by ahigh-ranking officer says to me that the importance of humanfactors/ergonomics is being recognized.It is also clear that a wide range of government organizationsworldwide have recognized the importance of HF/E to their mission.Here are a few examples to illustrate my point:• The Federal Aviation Administration has long recognized theimportance of HF/E and has well-established processes andguidelines in place. It has a Human Factors Research and EngineeringDivision.• The U.S. Nuclear Regulatory Commission has a human factorsprogram plan that grew out of the Three Mile Island incident.• The U.S. Food and Drug Administration has made a commitmentto ensuring the application of human factors engineeringto the design of new products.Similar governmental recognition of human factors and ergonomicsis evident around the world. For example, Transport Canadarequires all employees with technical responsibilities to havehuman factors training. Great Britain’s Health and Safety Initiativerecognizes the broad array of human factors issues. The PetroleumSafety Authority of Norway has selected improvements related tohuman factors issues in drilling operations as one of its primaryfocus areas for the next few years.These examples are by no means exhaustive. It is difficult toclaim that “no one knows about the field of human factors and ergonomics”or why it is important when you see the range of organizationsthat have incorporated the discipline into their centraltenets. Of course, I recognize that we still have a way to go to ensurethat funds are provided to support these initiatives and toensure that qualified individuals are hired to instantiate the guidelinesand enforce the regulations. Nevertheless, being recognizedand respected does not appear to be a problem.In the courts, experts in HF/E have much to contribute to thedispute resolution process in areas such as driving accidents, productliability, and industrial accidents. Importantly, the field is increasinglybeing recognized by the courts and by lawyers who arehiring such experts to help jurors understand why events have happened.Often these cases can be explained as design-induced errors,and individuals with expertise in HF/E can help to explain thefacts of the case.Another indicator of the prevalence of HF/E is the variety ofcompanies that HFES members work for, including transportationindustries, telecommunications, health care and insurance,the computer industry broadly defined, companies that cater to thehome or to leisure activities, and so many more.In addition, the future looks bright for employment opportunities– a recent search of a popular job site revealed 337 jobs withthe keywords human factors and 257 jobs with the keyword ergonomics.continued on page 2HFES BULLETIN • NOVEMBER 2005 1

Cuevas, NEM Committee CochairAt the HFES 49th Annual Meeting in Orlando, HFESPresident-Elect Marvin J. Dainoff kicked off National ErgonomicsMonth (NEM) 2005 at a special session by inspiring a packedroom with his vision for the future of our profession. He cited theneed to attract new, young members to the Society and to encouragethem to become actively involved in the field. He also emphasizedthe need for every Society member to get the word out tothe public on the importance of human factors and ergonomics(HF/E) through outreach initiatives such as NEM and throughmore effective efforts to translate research into practice.Keynote speaker Mark Lee Edwards, formerly managing directorfor Traffic Safety Programs at the American Automobile Associationand now working as an independent consultant, providedvaluable advice on how to work with government representatives.He recommended that you know their mission, speak their language,address an existing/known problem, stifle your scientificcuriosity about related topics, and relate your proposal to theirmission.Awards were presented for two contests designed to encourageHFES members to become more actively involved in promotingHF/E in their local communities. The NEM 2005 Best ActionPlan Contest first place award (plaque and $100) went to the HFESVirginia Tech Student Chapter. Special recognition was given toHFES student chapters at Georgia Tech and the University ofCentral Florida, and to Hugo Bertolotti from the HFES Cal StateLong Beach Student Chapter for their excellent action plans (seethe October HFES Bulletin for summaries).The NEM 2005 Best Action Plan Implementation Contestrecognized HFES members who successfully implemented the activitiesthey proposed in the previous year. First place went to theHFES University of Central Florida Student Chapter. In secondplace was the HFES Old Dominion University Student Chapter.The NEM Committee thanks the members of the selection committeefor both contests: Arnold M. Lund, Christina CostanzoMendat, Ellen M. Carpenter, and Monica Philippart.During the “Games to Explain Human Factors” session, theprize for “hardest-working volunteer” went to Linda Upham-Ellis(University of Central Florida). Beth Meyer (Semilla Consulting)came in second, and Julie Naga (George Mason University) placedthird. All attendees received a small gift for sharing their ideas andwere encouraged to take special stickers and custom bookmarks todistribute during their activities for NEM in October.SCIENCE FORUMHFES Sponsors HomelandSecurity ForumOn November 17, 2005, HFES will cosponsor a day-longScience Forum in Washington, D.C., on the topic of homelandsecurity. Recent events have demonstrated a clear and obviousneed for research in the behavioral sciences to be considered andproperly applied to policies, procedures, and technology related tothe nation’s security. However, there are many obstacles in gettingthat work funded and applied to policy.This year’s forum, “Human Factors Research and HomelandSecurity: Current and Future Applications,” will serve to informagencies such as the National Science Foundation, Department ofDefense, and Department of Homeland Security about importantwork being done by HF/E professionals.The morning session will feature a panel in which human factorsresearchers describe both the potential applications of theirresearch toward the improvement of the nation’s homeland securityand the need to increase the presence of human factors researchwithin the Department of Homeland Security and related agencies.The afternoon session will highlight a panel of federal agencyrepresentatives offering perspectives on opportunities for humanfactors research within their respective agencies. Panel membersand meeting attendees will have several opportunities for groupdiscussions, with an emphasis on the future role of human factorsresearch within those federal agencies dedicated to homelandsecurity.This forum is second in what is envisioned to be an annual collaborativeevent with the Federation of Behavioral, Psychological,and Cognitive Sciences. Such science forums are designed to raiseawareness of human factors research and applications and to educatethe human factors community about the best ways to approachfunding opportunities.If you are interested in attending the forum, please contactHFES Executive Director Lynn Strother at 310/394-1811, lynn@hfes.org.HFES BULLETIN • NOVEMBER 2005 5


STUDENT CHAPTERSLOCAL CHAPTERSCalendar Fundraiser FeaturesFamous HF/E FacesBy Jennifer Ross, HFES UCF Student Chapter Public AffairsChairLast June, members of the HFES University of Central Florida(UCF) Student Chapter were wracking their brains for an activitythat would allow them to be creative, learn more about some ofthe major players in the human factors/ergonomics field, and providea vehicle to raise money for a small student research award.In response, members dreamed up the idea of creating the firstcalendar to highlight the famous faces of human factors.Twelve big names in the field agreed to let chapter membersmanipulate photographs of them. The pictures were morphed intofamous movie stills, which slyly highlight each pioneer’s area of researchinterest. For example, in the calendar you can see Joel Warmstarring in “The Hunt for Critical Signal,” a parody of the movieThe Hunt for Red October. Other HF/E personalities in the calendarare Melody Carswell, Haydee Cuevas, Marvin Dainoff, Mica Endsley,Peter Hancock, Donald Norman, Raja Parasuraman, WendyRogers, Kay Stanney, Eduardo Salas, and Chris Wickens.The calendars were unveiled at the HFES 49th Annual Meetingand were such a success that the student chapter has increasedthe print run. All additional profits from the calendar will be sentto the Red Cross relief effort for victims affected by HurricanesKatrina and Rita. If you would like to order your very own “FamousFaces of Human Factors,” please complete the order form athttp://www.psych.ucf.edu/hfes/2006calendar.php and include a check,cash, or money order for the calendars to HFES UCF StudentChapter, c/o Jennifer Ross, University of Central Florida, 3100Technology Pkwy., Ste. 335, Orlando, FL 32826-0544.NCSU Students Plan MentoringProgram with IBMThe HFES North Carolina State University (NCSU) StudentChapter will partner with IBM to provide a professional mentoringprogram for students in both the Psychology and IndustrialEngineering Departments at NCSU.The chapter’s newly formed subgroup, NCSU Human FactorsBusiness Outreach Program, formed an alliance with IBM-Research Triangle Park. With the aid of IBM’s Linda Brown andChris Pepper, the chapter is pairing students with IBM employeesto provide a close mentoring relationship, allowing studentsinsight into the application of human factors/ergonomics principlesin an industrial setting.IBM employees taking part in the program include both humanfactors hardware and user interface software specialists. In addition,students will be invited to the IBM Research Triangle Parkcampus to take part in a number of activities, including tours offacilities otherwise inaccessible to the public.For more information on this exciting opportunity, please contactHFES NCSU Student Chapter President David Windell atdwindell@gmail.com.Puget Sound Chapter OutreachActivitiesFor the second year in a row, HFES Puget Sound Local Chaptermembers volunteered to help with the School-to-Work sessionat the Washington state governor’s Industrial Safety andHealth Conference in Tacoma, WA. Members taught ergonomicsprinciples to more than 80 local high school students throughhands-on activities that included how to set up a computer workstation,hand tool versus power tool use in a repetitive task, postureand lifting demonstrations, and how to design the control knobburnerrelationship for a stove top. The students especially seemedto enjoy being hooked up to the Pocket Ergometer, which convertsthe electrical activity associated with muscle use into sound. Studentswere able to hear the difference between neutral and awkwardpostures and between wearing a backpack with one strap or withtwo. Anyone looking for ideas about demonstrating ergonomics tostudents can get more details on these activities, as well as a copy ofan ergonomics video appropriate for high school students, bycontacting Rick Goggins at pastpresident@pshfes.org.Goggins was also the featured presenter at an HFES PugetSound Chapter dinner meeting focusing on ergonomics in schools.Topics included statistics on student injuries, current informationavailable for school ergonomics, and what teachers want to knowabout ergonomics.SHORT COURSES27th Annual Occupational Safety and Health Update, December8–9, 2005, Chapel Hill, NC.

It very nicelyillustrates how combinations of age, gender, and common sensory and motor impairmentsalter the performance capability of various groups. Some quantitative design recommendationsare included, though it also is made clear that much more needs to be learned about “extraordinary”populations to substantiate specific intervention strategies in the future.– Don B.
